Subject: CVE request: kernel: niu buffer overflow for ETHTOOL_GRXCLSRLALL

"niu_get_ethtool_tcam_all() assumes that its output buffer is the right 
size, and warns before returning if it is not.  However, the output 
buffer size is under user control and ETHTOOL_GRXCLSRLALL is an 
unprivileged ethtool command."

Affects kernel v2.6.30-rc1 onwards.

Thanks, Eugene
